Precision stamping die industry strong momentum of development

Stamping die in the new energy, automation equipment, medical equipment, aerospace and energy saving products such as mold development momentum. This year's Guangzhou International Mold Fair exhibitors in the precision multi-position progressive die occupy the status of mainstream products, not only the number of exhibitors and varieties of coverage, and mold quality and technical content is also much higher than the previous mold show.

International Mold Association Secretary-General Luo Baihui said that in recent years, advanced precision stamping die to upgrade the overall technical level soon, the mold technology, manufacturing accuracy, life and manufacturing cycle performance indicators have improved significantly, a considerable part of high-grade The overall level of high-quality mold has reached or close to the international level of similar mold. Such as Gree Daikin Die Co., Ltd. production of fins progressive die life of up to 500 million times, the scale of production and technological development and other aspects of a leading position in the country. The developed 0.4mm pitch high precision miniature connector progressive die has a precision of 0.5 and the smallest punch 0.13mm is directly polished to the mirror surface to ensure that the pin of the workpiece is 0.17mm, the bending accuracy is 0.01mm and the S-shape Bending and other high-precision requirements. Shenzhen, a motor mold produced by the motor core automatic laminating progressive die, the service life of up to 150 million times more than the level of technology and laminated technology has been close to the foreign advanced level of similar mold. The development of the 0.5m diameter in 400 tons of high-speed punch on the production of large-scale iron chip progressive die, 0.88m square iron chip with 90 rotating large precision composite block module and 1.2m diameter rotor sheet of large precision die and other specialized Production level and capacity in the domestic leading position.

Specialization to stamping die innovation capacity greatly improved, the technical level to the special, refined, excellent, strong direction, the emergence of many high-tech precision stamping die and new technology. It is reported that the urgent need to display the air-conditioning fins step precision die, to meet the five types of sheet-shaped fast switching production, with a certain degree of flexibility of production characteristics, mold level and international advanced level. Exhibit the lead frame 37-stage progressive die, a mold three, in 1212mm within the punching system of 48 inner and outer lead legs, the minimum spacing 0.12mm, flatness of the product within 0.01mm. Its high-speed batch production performance and life with the international advanced level, and structural innovation patents.

Many domestic precision stamping die in life and the main performance compared with the international advanced level, the gap is getting smaller and smaller, part of the overall level of precision stamping die with the international advanced level, not only completely replace imports, and a considerable part of mold exports to the United States , Japan and other industrialized countries and regions. China's overall level of precision die close to the international advanced level, a considerable part of precision die is out of the country, to participate in international competition.
